PlLE-WIRE.

SPECIFICATION forming part of Letters Patent No. 788,229, dated April25, 1905. Application filed December 11, 1903. Serial No. 184,735.

To all whom it may concern.-

Be it known that I, WILLIAM WATTIE, a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts, have invented certain new and useful Improvements inPile-Wires, of which the following is a specification.

My invention relates to that class of looms for weaving pile fabrics inwhich the pilewires over which the loops are formed extend in thedirection of the length of the warps, and my invention particularlyrelates to the pile-wire and its supporting-blade.

Heretofore in the class of looms referred to the pile-wires have beenpermanently attached to their supporting-blades, and in ordinary casesthe pile-wires have been rigidly attached so that there is noindependent movement of the pile-wires or of their supporting-blades. Inthe United States Letters Patent No. 7 17,5237, dated December 22, 1903,is shown and described a pivotal attachment of a pilewire to itssupporting-blade, so that the pilewire may have a movement independentof its supporting-blade; but in this case the pivoted pile-wire ispermanently attached to its supporting-blade and cannot be detachedtherefrom without removing the blade and its supporting-heddle from theloom.

I have found in practice that in operating the class of looms abovereferred to it is often desirable to detach and remove the pile-wiresand substitute others having a higher or lower end, over which the loopsare formed, according to the height of the pile-loop desired or thethickness of the pile. It is also desirable to do this as expeditiouslyas possible and without interfering with or removing any other parts ofthe loom, particularly the heddles and the blades supporting thepile-wires attached to said heddles.

The object of my invention is to improve upon the construction of thepile-wires and their supporting-blades as ordinarily made and which arepermanently attached together, as above described, and to make apile-wire which can be readily detached from its supporting-blade, aswill be hereinafter fully described.

I have shown in the drawings my improvements applied to a heddle and asupportingblade for the pile-wire of a similar construction to what isshown and described in the Letters Patent No. 7 47 ,587, above referredto.

Referring to the drawings, Figure 1 is a side view of a heddle, asupporting-blade, and a pile -wire embodying my improvements. Fig. 2shows, on an enlarged scale, the upper end of the supporting-bladedetached and partially broken away and the detachable end of thepile-wire. Fig. 3 is a section on line 3 3, Fig. 2, looking in thedirection of arrow (4, same figure. Fig. i is a section on line 45 4,Fig. 2, looking in the direction of arrow 6, same figure. Fig. 5 showsthe pile wire shown in Fig. 1 detached, and Fig. 6 shows a modifiedconstruction of the pile-wire shown in Fig. 5.

In the accompanying drawings, 1 is a strip or bar of flat metal, whichmay be termed a guide-strip, and is made, preferably, with an offset orbend 1' therein near its central portion. The strip 1 may be stationaryin the loom or may have a slight vertical motion. To the lower end ofthe strip 1 is permanently attached, preferably by rivets 2, the lowerend of the pile-wire-supporting blade 3. The upper free end of the blade3 is preferably substantially in line with the offset 1 in the strip 1,as is customary.

The pile-Wire 1 is preferably made of flat metal and of substantiallythe shape shown, with the straight end 1', over which the pileloops areformed in the usual way. The other end of the pile-wire 4 is preferablymade hookshaped, as shown at 4. The hook 4" is in this instance adaptedto loosely fit into an eye or socket 3 at the upper end of the blade 3.The hook end 4 of the pile-wire 4, fitting into the eye or socket 3 inthe,blade 3, makes the pile-wire A readily detachable from the blade 3.

In Fig. 6 is shown a pile-wire 5, made of flexible wire to allow of theyielding or bending of the pile-wire between its straight end 5' and itsdetachable end 5 in case of any vertical movement of the blade to whichit is attached.

I have shown in the drawings one way of detachably connecting thepile-wire with its supporting-blade; but it will be understood that I donot limit myself to this particular way, as any other way of detachablyconnecting the pile-wire to its supporting-blade may be employed.

The advantages of my improvements will be readily appreciated by thoseskilled in the art.

By the term detachable as used in the claims I mean such a connection aswill permit the ready removal of the pile-wire from its support withoutinterfering with or removing any of the parts of the loom or heddles,whereby another pile-wire may be substituted therefor.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a loom of the class described, the combination with an individualupright supporting-blade, of a pile-wire detachably connected connectiontherewith.

4:. In a loom of the class described, the combination with a strip orbar and a pile-wiresupporting blade attached thereto, of a pilewiredetachably connected with saidv blade to be readily removable therefrom.

5. In a device of the character described, the combination with astripor bar having an offset or bend therein, a pile-wire-supporting bladecarried by said heddle, of a pile-wire detachably connected to saidblade to be readily removable therefrom.
